So I am thinking of trying an idea I saw here somewhere (memory shot, lol). Said to very, repeat, very lightly score the top of the hinge with sharp xacto knife to free it up some. Cut through the welders that I put on.

Stuball. Welders along the entire hinge line is probably too much. I made that mistake on my Edge when they first came out. It was a bit dodgy but what I did was bent the surface to stretch the glue and very very carefully ran the tip of a #11 blade along it. Going by feel and sometimes it would take a few light passes until I could feel that I had reached the foam but not cut through it. The tape you have at the ends should be enough so anything in between that is just stiffening your hinge in my experience.

2s or 3s!!! that's the beauty of the stock power set. Change the prop, change the pack and change the beast your flying it really doesn't matter as long as your having fun and with the Pitts that's a given.

i run a small bead of welders all the way down the hinge line and then fold it back and wipe the hinge with my finger to get a thin coat all the way down the line,a little stiff at first but my suface doesn't come apart

Well, she has flown. Wow, I very pleasantly surprised. She flys superbly. No trims required and straight into hangs and harriers. This baby kicks ass!
She also handled the wind very well. Flew the CY as well to compare.
It was an excellent maiden and no damage!

That's what I've been waiting for Jimbo. Can't argue with that for a maiden, your rolling circles are really coming on. That flying field of yours is great, masses of room. How are you getting on with your ExtraVaganza?
